Resumo: 	In the State of Santa Catarina there is no information about haematological and parasitological characteristics of fish maintained in feefishing operations and manured ponds. This work compared the haematological characteristics of Nile tilapia parasitized or not, captured in a property situated in Nova Trento, SC, Brazil, between August 2003 and July 2004. During the studied period, the water temperature, pH, dissolved oxygen, alkalinity, ammonia and transparency were measured. Ten fish were collected monthly either in a feefishing or in a pond receiving pig manure, and anesthetized with benzocaine solution for haematological, parasitological and histopathological exams. From a total of 360 analyzed fish, 64 (17.8%) were parasitized with Cichlidogyrus sclerosus and Cichlidogyrus sp. (Monogenoidea: Ancyrocephalidae), 20 (5.5%) with Trichodina sp. (Protozoa: Ciliophora), and four (1.1%) with Lamproglena sp. (Crustacea: Lernaeidae). The total number of erythrocytes, thrombocytes and leucocytes, glucose rate and the percentages of hematocrit, lymphocytes, monocytes and neutrophils did not show relation with parasitism. Histopathological analysis showed moderate hyperplasia and absence of congestion. The low level of parasitism found in the animals was not responsible for haematological alterations.
